Ingredients

Scale

Dry Ingredients

  • 2 cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter, room temperature
  • 1½ cups granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract

Filling

  • 1 cup marshmallow fluff or 12 large marshmallows, cut into pieces

Instructions

  1. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt to ensure they are evenly combined. Set this mixture aside.
  2. Cream Butter and Sugar: In a large mixing bowl, use an electric mixer to cream the room temperature unsalted butter and granulated sugar together until light and fluffy, which should take about 3 to 4 minutes. This step is essential for a tender cookie texture.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time to the butter mixture, fully incorporating each before adding the next. Then add the vanilla extract and mix well.
  4. Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the wet ingredients while mixing on low speed. Mix just until combined to avoid overworking the dough, which can make the cookies tough.
  5. Chill the Dough: Cover the dough with plastic wrap and refrigerate for at least 1 hour. Chilling helps firm up the dough, making it easier to handle and enhancing the final texture.
  6. Prepare for Baking: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking and promote even baking.
  7. Shape Cookies and Add Marshmallow: Scoop out portions of the chilled dough and roll into balls. Place them on the prepared baking sheets spaced about 2 inches apart. Press a small indent into the center of each dough ball and spoon a teaspoon of marshmallow fluff or a small piece of marshmallow into the center. Using a toothpick, gently swirl the marshmallow into the dough for a marbled effect.
  8. Bake the Cookies: Bake the cookies for 10 to 12 minutes in the preheated oven until the edges are set but the centers remain soft. For extra gooeyness, you can optionally add a little more marshmallow fluff on top halfway through baking.
  9. Cool: Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes. Then transfer them to a wire rack to cool completely before serving to ensure the marshmallow swirl sets nicely.

Notes

  • For best results, make sure ingredients like butter and eggs are at room temperature before starting.
  • Using marshmallow fluff will give a smoother swirl, but chopped marshmallows also work well for added texture.
  • Do not over-bake; the centers should remain slightly soft for the perfect gooey texture.
  • Store cookies in an airtight container at room temperature for up to 3 days or freeze for longer storage.
  • You can use dark or semi-sweet cocoa powder depending on your preferred level of chocolate intensity.
